SharePoint 2013 permissions for each user

Question

I am working on my own SharePoint 2013 test site and I need to grant permission to the test accounts. I want to make certain the 3 test accounts can not see the lists, files, and workflows that the other users created.
Do I need to grant permission at the site level, user level, custom list level, for each workflow, and/or for each custom form? Do I invite each user and/or 'share' with each user? Can you tell me and/or point me to a source that will tell me what level
of permission I need and how to grant this type of permission?

Answer 1

Wendy,
In sharepoint, you can grant permission at any level you want. That permission will carry forward by default until someone break them and configure unique permission.
In ideal case, we recommend to use share security group to grant permission and not grant to individual user. Also try to restrict 2 default site group (Owner/member/viewer) as much possible, but in reality ppl break these rule often and eventually end up
with maintenance overhead.
I will recommenced you and everyone to go through this nice ppt which clears sharepoint permission idea in our mind.
